The preproduction samples by our quality assurance department are tested by the laboratory technicians for:
(1) Surface finish;
(2) Dimensional accuracy of test samples;
(3) Date from extrusion and injection molding machines.
The goods will be released for production only if optimal test results are achieved. These tests are carried out at the beginning of each production series to ensure perfect quality for piping systems.
Final Inspection And Test.
Finished products are only released to stock when all tests and inspections conform to the prescribed procedures, which include:
